Pressure is stagger heavy. And I find it kind of hard to really explain it to people lol, honestly you just gotta go in there and find out what works for you and try things out. But her most notable normals in pressure are 5B and 5C. 5C is a really good pressure tool since it's special and jump cancel-able (and dash cancel-able, if you're into that) and it gatlings into sweep and is also a reverse beat, so things like 5C into 5B are possible. S.Naoto's pressure isn't as good as regular Naoto cause S.Naoto doesn't have the same auto combo.
So I guess some cool gimmicks would be things like short hop>J.C>J.214CD into either roll, neutral jump delayed airdash, or just a jump in low. Her short hop J.C is pretty decent if your opponent isn't calling you out on it. Also she gets good reward off successful throw baits, so go for throws. 2[C] is +8 on block so if you get it you are at an extreme advantage. But most important is mixup your blockstrings so you don't get called out and eat a combo. Oh yeah and lastly throw in a couple aim cancels and trap cancels from like 5B and sweep (8 frames of godliness and low profiles).
Also 5B>5C>236A=Netplay unblockable
